Title: Filter coefficient revision system for digital filter
Inventor: NAGAMI MASAAKI
IPC: H03H17/04
Filed: 1989-03-24
Abstract: PURPOSE:To prevent noise production and oscillation at the time of revising by storing plural sets of filter coefficients to a filter arithmetic section, allowing the filter arithmetic section to any of plural sets of the filter coefficients to apply filter arithmetic operation. CONSTITUTION:Plural sets of filter coefficients 42 are stored to a filter arithmetic section 40, and a control section 50 sends a command to select any set of the plural sets of filter coefficients and the filter arithmetic section 40 selects any set of the plural sets of the filter coefficients 42 in response to the command to apply filter arithmetic operation. Since the command requires only 1 word, the time required for the transmission and reception is far shorter than the time required for the transmission reception of all the coefficients of the filter. Moreover, since the filter arithmetic section 40 has only to select the set of the filter coefficient in response to the command, the filter coefficient is switched without giving effect on the filter calculation with one arithmetic period. Thus, noise at the time of switching is not caused, and the possibility of oscillation is precluded.

Title: Paper separating device
Inventor: YOSHIMURA HARUYOSHI
IPC: G03G15/14
Filed: 1988-03-23
Abstract: PURPOSE:To prevent the damage of photosensitive material such as a photosensitive body, which is caused by a paper separating claw, by a simple expedient by vibrating the claw together with its retreat. CONSTITUTION:On retreating, the paper separating claw 1 reciprocates in the axial direction of the photosensitive body 4, that is, vibrates, in synchronization with the turn of a turnable axis 6 in a direction shown by an arrow. At this time, the tip 7a of a cam 7 is T-shaped, and therefore it can retreat regardless of the movement of the paper separating claw 1. In such a way, a solenoid 8 doubling as a driving source controls the retreat and vibration of the paper separating claw 1, thereby synchronizing both actions automatically. Only when the paper separating claw 1 retreats completely, it is vibrated. Thus, the photosensitive body 4 is never damaged, and moreover its own control mechanism can be simplified.

Title: Control system for application of power supply
Inventor: KARUBE AKIRA
IPC: G06F1/00
Filed: 1987-03-24
Abstract: PURPOSE:To realize the effective application of a power supply by recording previously the information on the presence/absence of connection of a device to a memory part of a service processor and controlling the application of the power supply when the power supply is switched on. CONSTITUTION:The presence/absence of connection of devices is registered in a memory part of a service processor 3, e.g., a floppy disk 3-1 for each connector of a power supply controller. The processor 3 monitors the connection end signal received from a connector and collates this signal with the disk 3-1 to perform the processing of the next step even though the connector has no response, i.e., in case no device is connected. Thus, the application of a power supply is secured with high efficiency. As a result, no short circuit connector is needed and the processor 3 can confirm the power supply application state via a display device. Thus, the efficiency and the reliability can be improved for application of a power supply.

Filed: 1989-03-23
Abstract: PURPOSE:To set a prescribed temperature for HOT sales at any time by providing a heating coil wound to a circular plate shape, and two temperature detectors, which detects the can wall temperature of a cover on a non-contact basis. CONSTITUTION:A heating coil 1, which induction-heats a canned beverage and is wound to a circular plate shape, and two temperature detectors 5 and 6, which detect two facing covers of the canned beverage induction-heated on the heating coil 1 on a non-contact basis, are provided. Further the detected two temperature detecting outputs are added by an adding means 8, decided by a deciding means 9, and a high frequency power converter 3 is controlled based on a decision result. Since the heating coil is in the circular plate shape, a trouble that the temperature of the small can cannot be detected because the can is hidden in the heating coil is eliminated, in addition, since the can wall temperature during heating is detected on a non-contact basis, the reliability is improved. Thus the prescribed temperature for HOT sales can be maintained in any case.
